Gas-spring monitor arm for 17–30 inch monitors up to 19.8 lb — full-motion adjustment, C-clamp and grommet mounts.
Buy if your monitor is 17 to 30 in and weighs 4.4 to 19.8 lb without its stand, and you want smooth gas-spring height adjustment with full-motion tilt, swivel, rotation and pan, plus both C-clamp and grommet mounts in the box.
Skip if your panel is above 19.8 lb (the lowest ceiling of the three arms reviewed) or below the 4.4 lb gas-spring floor, or you want detailed assembly instructions — owners call them minimal and recommend a helper for the final attachment.
Check Price on Amazon →NB North Bayou F80 review: a gas-spring monitor arm for 17 to 30 inch monitors up to 19.8 lb with smooth full-motion adjustment and C-clamp or grommet mounting. Owner feedback centers on the smooth gas-spring lift and position hold. The consistent limits are minimal assembly instructions and a 19.8 lb ceiling that rules out heavier professional displays.
| Max Monitor Size | 17-32 inches |
|---|---|
| Max Weight | 19.8 lbs |
| VESA Compatible | 75×75mm and 100×100mm |
| Adjustments | Height, tilt, swivel, rotation, pan |
| Cable Management | Integrated channel |
| Clamp/Bolt | Both included |
| Gas Spring | Yes — smooth adjustment |
The gas-spring mechanism is the differentiator owners cite most: adjusting monitor height takes little force, and the arm holds position once set, unlike cheaper friction-based arms.
Full-motion adjustability — height, tilt, swivel, rotation, and pan — covers the standard ergonomic adjustments. Both C-clamp and grommet mount options are included.
Owners consistently describe the arm as not feeling like a budget product in daily use, with smooth movement and a stable hold.
That hold is tunable rather than fixed, which owners single out once they understand it: the manual rates the gas spring for 2.0 to 9.0 kg (4.4 to 19.8 lb) and gives the tension screw a direction for each symptom — a panel that sinks gets turned toward “+”, a panel that floats up gets turned toward “−” — so the arm can be dialed to the panel it actually carries instead of shipping at one compromise setting.
Max weight of 19.8 lb won't handle ultra-heavy professional monitors. For those, you'll need a heavier-duty arm.
The assembly instructions are minimal — owners recommend allowing 15 to 20 minutes for installation and having a helper for the final monitor attachment step.
The included plastic cable clips feel flimsy to many owners; Velcro ties are the common upgrade for a cleaner look.
The weight range has a floor as well as a ceiling, and both ends need measuring, not guessing. The figure that counts is your monitor's weight without its factory stand, from the manufacturer's specification page: a panel above 19.8 lb is outside the rating outright — the lowest ceiling of the three arms we review — and a very light panel under the manual's 4.4 lb minimum sits below what the gas spring is tensioned to balance, so it may not stay lowered the way a mid-weight panel does. Capacity is best judged with headroom left over at the top end rather than at the line.
Owner reports describe a steady hold on standard 24 to 27 inch monitors over long-term daily use, with no drift or sag once tension is set toward the monitor's weight. The gas-spring adjustment is repeatedly described as smoother than friction-based arms, and owners report little wobble during typing.
The pattern in owner feedback is that tension-setting decides the experience: a gas spring only balances the panel it is tensioned for, so the reports of an arm that sinks or floats up almost always trace back to the tension not yet being dialed to the panel's actual weight, while owners who work through the manual's “+” and “−” fix describe the screen staying where it is left. At full extension the leverage on a heavy panel multiplies the effective load, so a panel near the 19.8 lb ceiling is the case where that dialing matters most — and the case a higher-capacity arm handles more comfortably.
Anyone who wants gas-spring adjustability and a long owner track record in a single-monitor desk arm for a standard 17 to 30 inch monitor under 19.8 lb. Running a wider panel? Our ultrawide monitor arm guide runs the weight and headroom numbers on this arm against 34-inch panels — including where its 19.8 lb capacity becomes the limit.
This arm carries three hard limits: monitors from 17 to 30 inches on the conservative size range its manual states (some listings show a wider range; this review follows the manual, as our other monitor arm pages do), a weight range of 4.4 to 19.8 lbs — the manual's 2.0 to 9.0 kg — and VESA mounting patterns of 75×75mm or 100×100mm. Everything else about fit follows from those numbers, so check them against the monitor you actually own — its weight without the factory stand and its VESA pattern, both from the manufacturer's specification page — before anything else on this page matters.
Weight is the limit owners most often misjudge, and this arm punishes the mistake at both ends. A monitor's listed shipping weight includes the stand and the box, and its on-desk weight includes the stand the arm replaces; the arm only ever carries the panel itself. Judge the panel-only figure against the 19.8 lb ceiling with headroom to spare — the weight-capacity guidance in our ultrawide monitor arm guide works through why a rating is best treated as a ceiling to stay visibly under, not a target to land on. The floor matters too: a gas spring is balanced for a minimum load, and a panel under the stated 4.4 lb minimum is outside the range it is tensioned for.
VESA is the quiet disqualifier. Most standard 17 to 30 inch monitors carry a 75×75 or 100×100 pattern and mount directly; some panels hide the pattern under a cover or need the manufacturer's own adapter, and large professional displays that use 200×100 are outside what this arm accepts at all. If your monitor has no VESA pattern, no arm in this price class fixes that — check the back of the panel before you order, not after.
| 17 inches | Fits, at the low end | The smallest size in the manual range this review follows. Check the floor as well as the size — a very light small panel can sit under the 4.4 lb minimum weight. |
| 24 inches | Fits comfortably | Well inside the size ceiling, and panel-only weight is typically far under 19.8 lb. Confirm the VESA pattern. |
| 27 inches | Fits | The size this arm is most often bought for. Heavier professional 27 inch panels sit closer to the 19.8 lb ceiling — check panel-only weight before relying on the headroom. |
| 30 inches | Fits, at the ceiling | The stated maximum size on the manual range. Weight, not inches, decides: a 30 inch panel near 19.8 lb without its stand leaves no headroom. |
| 32 inches | Outside the published range | Above the 17 to 30 inch manual range this review follows, whatever it weighs. A panel this size belongs on an arm whose own stated range includes it. |
| 34 inch ultrawide | Outside the rating | Above the stated size maximum before weight is even considered. Our ultrawide guide runs the numbers on all three arms we review against 34 inch panels. |
| VESA 200×100 | Outside the rating | This arm accepts 75×75 and 100×100 only. A 200-pattern panel needs an arm that lists it. |
Ergonomic guidance for seated computer work — the OSHA workstation guidance our laptop stand posture guide is built on — puts the top of the screen at or just below eye level, the screen roughly 20 to 40 inches from your eyes, and your gaze angled slightly down, around 15 to 20 degrees. A monitor on its factory stand often fails the first test by a fixed amount you cannot change: the stand gives you one height, and your chair and desk were not designed around it. Height adjustment is the entire reason an arm exists — and a gas-spring arm with pan as well as tilt, swivel, and rotation is the version of that adjustment you can fine-tune with one hand, including the screen's angle toward you, not just its height.
You can measure your own gap in about a minute. Sit in your normal chair at your desk, look straight ahead, and note your eye level against the wall or a door frame. Then compare it with the top edge of your screen as it sits today. If the top of the screen sits well below eye level, you are looking down at a steeper angle than the guidance suggests all day; if it sits above eye level, you are tilting your head back. An arm closes that gap in either direction and, just as usefully, lets you pull the screen to the right viewing distance without moving the desk.
If the screen you are raising is a laptop rather than a monitor, the fork is different — a laptop stand against a monitor arm — and our laptop stand vs monitor arm guide works through which screen you own first. And if you are arranging the whole desk rather than one screen, the screen layer is layer one of the four-layer setup in our ergonomic desk setup guide.
All three arms we review mount a single monitor; what separates them is capacity, size range, and mechanism. The specifications below are each arm's own catalog figures, with this arm's size range shown at the conservative 17 to 30 inch range its manual states. This arm is the proven gas-spring pick of the three — the longest owner track record and the smooth frequent-repositioning choice — while the HUANUO carries more weight and the Amazon Basics arm trades the gas spring away for set-and-forget simplicity.
| NB North Bayou F80 (this review) | 4.4 to 19.8 lb · 17 to 30 in (manual) | Gas spring · smooth frequent repositioning, with pan |
| HUANUO Single | 4.4 to 22 lb · 13 to 32 in | Gas spring · the capacity pick of the three |
| Amazon Basics | Up to 20 lb · up to 32 in | Standard mechanism · both mounts included |
No — not within its rating. On the conservative size range its manual states, the arm is specified for monitors from 17 to 30 inches and 4.4 to 19.8 lbs, so a 34-inch ultrawide is outside the stated size maximum before weight is even considered. Our ultrawide monitor arm guide runs the weight and headroom numbers on all three arms we review against 34-inch panels, including the lightest panels owners keep on this arm and where its limits land.
Use the panel-only weight from your monitor manufacturer's specification page — the weight without its factory stand, since the arm replaces the stand. Do not use the shipping weight, which includes the stand and packaging. Then judge the figure at both ends: a panel at or very near 19.8 lbs is at the arm's ceiling, where any arm holds least comfortably, and a panel under the manual's 4.4 lb minimum is below what the gas spring is tensioned to balance.
Usually the gas-spring tension is not yet set for the panel's weight. The F80 manual's fix is directional: turn the adjustment screw toward “+” until a sinking panel stays put, and toward “−” for a panel that floats up. Tension fixes that case; if the panel itself is above the 19.8 lb rating — or near it at full extension, where leverage multiplies the effective load — only a higher-rated arm fixes it.
No. The arm accepts VESA 75×75mm and 100×100mm patterns only. Check the pattern on the back of your monitor — or in its specification page — before ordering; some monitors hide the pattern under a removable cover, and some have no VESA mounting at all, in which case no standard arm fits without the manufacturer's own adapter.
Both are included in the box, so the desk decides. The C-clamp grips the edge of the desktop and needs no drilling, which is why most owners use it. The grommet mount bolts through a hole in the desk — either an existing cable hole or one you drill — and suits desks whose edge the clamp cannot reach or grip. Either way, the desk itself has to be solid enough to carry the arm and monitor at the mount point, and owners recommend a helper for the final step of attaching the monitor.
Yes, in one specific way: the monitor's factory stand comes off the desk entirely and the arm's pole mounts at the desk edge, so the surface the stand occupied becomes usable again. The screen still needs the same viewing distance — roughly 20 to 40 inches from your eyes per ergonomic guidance — so on a shallow desk, check that the arm can hold the panel far enough back before relying on the reclaimed space.
The NB North Bayou F80 is the gas-spring pick for a standard monitor: smooth one-hand height adjustment, full-motion positioning, and both mounts in the box. Check the weight of your panel without its stand first — above 19.8 lb, you need a heavier-duty arm.
